@CsdRazZaStaR2 3 года назад

Good stuff. So docker simulates lambda and SAM uses the template to do that. Can something similar be done with dynamodb for local development? Or would you have to manually create the local db to follow your SAM template and configure environmental vars to use the right endpoint (local vs AWS)?

@BeABetterDev 3 года назад

Hi there CsdRazzaStar! Great question. I believe this is possible as you've specified. I think you would just need to ensure you have dynamodb local running as a separate process to keep it up and running.

@blamoism 2 года назад

Thanks for great video. Found a small gotcha, there is a small difference between the source code and the code in video. To get json from the api had to use the extension /Prod/helloWorld?personId=5 instead of /Prod/hello?personId=5

@kowshikjayakumar8405 3 года назад

Hi, how can we construct the CF template ? Anyone please guide me

@temitopetola 3 года назад

Thanks. I love how simplified this is. One question, for the !sub $(ServerlessRestAPI) is that autogenerated on the apigateway endpoint?

@BeABetterDev 3 года назад

Hi Tola, No problem. The sub function instructs sam to substitute the value of the ServerlessRestAPI resource in our YAML code at runtime. Since this value is not known until the resource is actually created, this kind of substitution is necessary. Hope this helps, Daniel

How do you set a breakpoint in the lambda function?

@Chuls1000 Год назад

A great video. Can SAM do mostly everything CloudFormation can or is it limited to serverless domain?

@haeso5 Год назад

SAM is a superset of CFN. A working template should work in SAM too

@harishdewangan2661 3 года назад

This is very useful info. One question: Can we configure CloudFormation to update lambda function to have layers (for dependencies) I don't want to have multiple lambda functions with their own dependencies if that can be shared. Also can this deployment be automated via Jenkins so that my team can use it ?

@argl1995 3 года назад

Yes we can add layers for lambda functions in AWS CloudFormation. I have done it in the past

@robertlozano6780 Год назад

lambda layers was what i saw yesterday for that. I think they mention it in the serverless developer portal (in the videos)

I can't find the link to install SAM locally… Is SAM the same as CloudFormation? Or am I missing something?

FAILED. Reason: Unresolved resource dependencies [ServerlessRestApi] in the Outputs block of the template. anyone who got the same error?

@BeABetterDev 3 года назад

Hi hidehiro, This error is usually thrown when you changed the name of the resource in the template.yaml file. If you changed the name of something, make sure you changed all occurrences of it on the template file. Hope this helps
